Abstract: Described is an apparatus which comprises: a first voltage regulator (VR) coupled to first one or more inductors, the first VR is to provide power to a first power domain; and a second VR coupled to second one or more inductors at least one of which is inductively coupled to at least one of the first one or more inductors, the second VR is to provide power to a second power domain separate from the first power domain, wherein there is a non-zero phase angle offset between switching transistors of the first VR relative to the second VR.
